Chimney And Flue; Maintenance; Safety - WANDERS Boreal Mode D'emploi

• Ventilate the space well when you have the stove on.
A crackling fire has a minimum air consumption of
25 cubic metres an hour. Never put on your cooking
hood when you have a stove burning in the same
space.
• Be careful with lighting the stove when it is foggy
or when there is no wind outside. There is hardly
any draught in the cold chimney when the weather
is calm. Since smoke is heavier than air there is the
chance of smoke streaming into the room. In foggy
weather, the smoke from the chimney (outside) cools
quickly and may descend and become a nuisance in
your neighbourhood.
• Don't smother the fire suddenly with water, but let it
burn out. The materials inside the stove may deform
or crack as a result of sudden or great differences in
temperature.
• If you want to temper the fire, first close the valve in
the flue tube and then close the air supply.

Chimney and flue

Chimney with a proper draught
Warm air wants to ascend. This is the principle of
every chimney. It helps when the wind near the
chimney mouth draws the air from the chimney.
Fall wind may give the opposite effect and blow
the air back into the chimney. Relatively cold foggy
air may thwart proper draught in your chimney as
does a long flue pipe with a rough inside and many
bends. If the natural draught in your chimney is
poor your installer can give you information about
using a ventilator for your flue tube.
The chimney is the most important part of your wood-
burning hearth.
When the chimney is right it will not distribute any smoke
into your room, leave any deposit on the glass pane or
create bad combustion. Before starting the installation
of the stove, your installer or a qualified chimney sweep
must check whether the chimney flue has a diameter
of at least 150 millimetres over the entire length, and
whether the channel is clean, smooth and leak-proof.
What to do in case of chimney fire.
In case of chimney fire, immediately close the
shut-off valve in the chimney and all air supply
ducts. Call the fire department. After the fire is
extinguished, the chimney and the stove must be
inspected again by your installer.

Maintenance

Small maintenance
• Remove the cooled ash from the ash pan twice or
thrice a week. It is advisable to use an ash bucket. An
empty ash pan is important since the stove also draws
in combustion air via the ash pan.
• It is advisable to leave an ash layer of two to three
centimetres. It will protect the fire plate.
• Clean the shaking grid inside the stove with a soft
brush.
• Clean the exterior of the stove with a damp cloth
that does not give off fluff. Do not use any aggressive
cleansing agents or abrasives.
• Clean the cold glass pane with a cleaning agent for
ceramic cooking rings. Do not touch the clean glass
with your fingers. Finger marks burn into the glass.
• Oil the hinges and the door fastener once in a while.
Do not use any aggressive cleaning agents or abrasives
to maintain your stove.
When the stove is not used
• Close all doors and air inlets in summer season
• Place absorbent salt inside the stove if it is stored in a
humid space.
• Rub some neutral Vaseline on the clean cast iron
stokehold parts.
Yearly maintenance
• Have your chimney properly cleaned by a qualified
chimney sweep every year; this is for safety reasons
and any fire insurance.
• Have the flue gas outlet and the combustion air supply
of the double-walled flue tube system checked for air-
tightness every year.
• Have the grate shaker checked for breakage.
• Have the valves and/or flaps checked for their
functioning.
• Have the sealing of doors and glass panes checked for
wear and tear.

Safety

A WANDERS wood-burning stove is a comfortable
and safe heat source in your home. Fire safety starts
with proper installation and a flue tube that is in good
working order. That is why your installer must adhere to
the installation requirements as given in page 22 and
further. To burn your stove safely, the following points
are important:
1. Burn your stove as much as possible with its door
closed; it will improve the output and is much bet-
ter for the environment.
2. Prevent small children or the infirm from getting
